Heat capacity of bomb calorimeter formula
WebIn a bomb calorimeter, the reaction vessel is surrounded by water that must be added for each experiment. Since the amount of water is not constant from experiment to … Web∆HcoC6H5COOH(s) = -3227 kJ mol-1 ∆HcoC6H5COOH x ( w / M2 ) = wc ∆T (where M2 = mol.wt benzoic acid). Knowing wc value, the enthalpy of combustion of any other substance is determined adopting the similar procedure and using the substance in place of benzoic acid. By this experiment, the enthalpy of combustion at constant volume ∆HcVol) is known
